As seen in the side view, the monitoring apparatus 100 includes a user interface 130 for the user to provide operation instructions and responses to the user authentication results of authenticators 101.

Referring to another side view (C) of FIG. 1, the user interface 130 includes several control buttons including at least a confirmation button 131, one or more selection buttons 132 and 133. For example, the monitoring apparatus includes several working modes corresponding to different types of users or working environment, the selection button 132 or 133 allows the user to chose certain procedures in response to a result of what the user identification information collected by the authenticator 101. The confirmation button 131 allows the user to confirm a certain working mode being chosen or simply start or end an operation of the UV radiation monitoring apparatus for recording a latest result of UV radiation exposure subjected to the user. Referring to this side view again, the mounting clip 120 has one end being attached to the back cover 112, allowing it to swing from a close position that is in touch with the back cover 12 to an open position that forms a V-shape slot 121 for facilitating it to be mounted to a target object.

FIG. 2 is a functional diagram of an apparatus for monitoring UV radiation and providing personal health instructions on UV protection according to some embodiments of the present disclosure. Referring to FIG. 2, in one of some embodiments, some functional components of the monitoring apparatus 100 are disclosed. In the embodiment, the monitoring apparatus 100 includes an authenticator 101 with partial exposure on the front cover 111 of a case 110 (see FIG. 1) for collecting user identity information. The monitoring apparatus 100 further includes a controller 103 coupled to the authenticator 101 to process the user identity information for determining whether a user is an authenticated user or an anonymous user. Optionally, the authenticator 101 can be a finger print collector or sensor for collecting finger print image or digital map. Optionally, the authenticator 101 is a voice sensor for collecting a passage of human voices. Optionally, the authenticator 101 is a sound sensor configured to detect a special sound spectrum generated by the user.

Referring to FIG. 2, the monitoring apparatus 100 also includes a memory 106 coupled to the controller 103. The memory stores multiple user identity information respectively loaded for different authenticated users. The controller 103 is configured to compare the just-collected user identity information with the user identity information pre-stored in the memory 106 to determine whether the current user is an authenticated user. In an embodiment, if the user identity information collected by the authenticator 101 is matched with the user identity information stored in the memory 106, the controller 103 is enabling a first working mode, e.g., an authenticated mode for the user as an authenticated user to operate the monitoring apparatus 101. The authenticated mode is enabling the controller 103 an access of a data base in the memory 106 associated with the authenticated user. Optionally, the data base is configured to store historical UV radiation exposure data and current UV radiation data for the authenticated user. Optionally, the memory 106 includes sufficient large size for establishing multiple data bases for multiple authenticated users. In another embodiment, if the user identity information collected by the authenticator 101 is not matched with any user identity information stored in the memory 106, the controller 103 is enabling a second working mode, e.g., an anonymous mode, for the user as an anonymous user to operate the monitoring apparatus 100. In the second mode, the controller 103 does not link to any data base associated to an authenticated user.

Referring to FIG. 2 again, the monitoring apparatus 100 includes a UV detector 105 including multiple UV radiation sensors disposed at multiple locations on either the front cover 111 or the back cover 112 or both (see FIG. 1). The UV detector 105 is configured to measure intensity of UV radiation applied onto the monitoring apparatus which is equivalent to a measurement of UV radiation exposure subjected to the user. In some embodiments, the UV detector 105 is configured to measure real-time UV light intensity at a present time. The UV detector 105 is coupled to the controller 10 so as to pass the measured UV light intensity to the controller 103 for generating a real-time ultraviolet index (UVI) value converted from the UV light intensity. At the same time, the controller 103 is configured to turn on a timer to measure UV exposure time of a current UV exposure event from start to a present time. A profile of UVI values with corresponding exposure time for the current event will be saved as a piece of UVI data being added to historical UVI data in the memory 106 for future use.

Referring to FIG. 2, the monitoring apparatus 100 further includes a display unit 89 coupled to the controller 103 to receive at least the real-time UVI value at the present time from the controller 103 for displaying the UVI value on a first display panel 108. Optionally, the first display panel 108 includes a circular shape to surround the authenticator 101. The UVI value is shown in numerical digits at least in part of the circular shape first display panel 108. Optionally, the first display panel 108 is configured to show different colors respectively coded with different ranges of UVI values to provide meaningful warnings. For example, for UVI values in a range of 0.0-2.9, the displayed color is green referring to “low” risk of harm from unprotected sun exposure. For UVI values in a range of 3.0-5.9, the displayed color is yellow for indicating moderate risk. UVI values in a range of 6.0-7.9 correspond to orange color for indicating high risk. UVI values in a range of 8.0-10.9 corresponds to very high risk with red color indicator. UVI of 11.0 and above corresponds to extreme risk with violet color indicator.

In an embodiment, the display unit 89 includes a second display panel 109 coupled to the controller 103 for displaying various personal health instructions on UV protection provided only when the monitoring apparatus 100 is working under the authenticated mode by an authenticated user. The personal health instructions on UV protection are generated based on the measured UVI value at the present time and historical UVI data stored in a data base associated with the authenticated user in the memory 106. The historical UVI data includes UVI values and corresponding exposure times at various environment conditions recorded at some historical periods of time for the particular user. Environment conditions include places with different altitudes, with different reflective surfaces like snow, water, sand or concrete, with different angles to the horizontal. Different persons with different natural skin colors or different ages or special requirements on UV exposure can receive different personal health instructions.

Referring to FIG. 2 again, the monitoring apparatus 100 also includes a user interface 130 coupled to the controller 103 and configured to receive user's inputs including certain operation instructions or responses to authentication results of the authenticator 101. In an embodiment as shown in FIG. 1, the user interface 130 includes one or more selection buttons 132, 133 and a confirmation button 131. The selection buttons can receive user's selection instruction for operating the monitoring apparatus to provide a target health plan on UV protection and send the selection instruction to the controller 103. The confirmation button can receive user's confirmation instruction for operating the monitoring apparatus to provide a target health plan on UV protection and send the confirmation instruction to the controller 103. For example, the user interface 130 may be used for a user to select and confirm if he/she wants to establish an authenticated user account when the user identification information collected by the authenticator 101 fails to match any one pre-stored in the memory 106. The user can select to stay as an anonymous user to operate the monitoring apparatus 100 as merely monitoring UVI value at the present time. Alternatively, the user may select to start establishing a new data base as an authenticator user to operate the monitoring apparatus 100 for providing UVI value at the present time as well as establishing a first historical UVI data starting from the present time by recording a profile of UVI values with a corresponding exposure time at the present location. This first historical UVI data will be saved in the data base associated with the newly authenticated user and used for generating personal health instructions on UV protection being displayed on the second panel 109. This first historical UVI data saved at this event can be retrieved in any future event by the controller 103 to generate personal health instructions on UV protection together with a real-time UV value obtained in the future event.

FIG. 3 is a functional block diagram of a system for providing personal health instructions on UV radiation protection according to some embodiments of the present disclosure. Referring to FIG. 3, the system 1000 includes a monitoring apparatus 200 configured to monitor UV radiation for an authenticated user and to be paired with a mobile terminal 500 hosted by the authenticated user to generate updated personal health instructions on UV protection. The monitoring apparatus 200 is substantially the same as the monitoring apparatus 100 (of FIG. 2) working in an authenticated mode, i.e., operated by a user whose identity information collected by the authenticator 101 is determined by the controller 103 to be fully matched with a pre-stored user identity information in the memory 106. A user data base in the memory 106 associated with the authenticated user now is openly accessible. Once a current UV radiation monitoring event starts, a real-time UV light intensity that the subjected monitoring apparatus 200 currently exposed is measured by a UV detector 105 installed thereof and is used to generate a UVI value at the present time by the controller 103. The monitoring apparatus 200 further includes a first display panel 108 of a display unit 89 for directly displaying the UVI value at the present time. The controller 103 further retrieves historical UVI data from the data base associated with the authenticated user in the memory 106. Based on both the UVI value at the present time and retrieved historical UVI data, the controller 103 is configured to provide personal health instructions on UV radiation exposure and protection and use a second display panel 109 of the display unit 89 to provide the instructions in text.

Referring to FIG. 3, the monitoring apparatus 200 further includes a communication interface 104 configured to link the monitoring apparatus 200 with a mobile terminal 500 that is hosted by the authenticated user. Optionally, the mobile terminal 500 is a smart phone. Optionally, the mobile terminal 500 is a tablet computer. Optionally, the mobile terminal 500 is a notebook computer. The communication interface 104 can be configured to provide either a wired connection or wireless connection with the mobile terminal. For example, the wired connection can be realized by a USB cable connected to two ports respectively in the monitoring apparatus 200 and the mobile terminal. Alternatively, the wireless connection can be realized through a short-range wireless communication network including WiFi, Zigbee. Bluetooth, and many other available technologies. The mobile terminal 500 is hosted by the same authenticated user for the monitoring apparatus 200 so that all data in the data base associated with the authenticated user in the memory 106 of the monitoring apparatus 200 can be backed up to the mobile terminal 500. At the same time, the data base associated with the authenticated user in the monitoring apparatus 200 can be synchronized with any new personal data in the mobile terminal 500.

In some embodiments, the mobile terminal 500 is configured to retrieve all historical UVI data in the data base associated with the authenticated user in the monitoring apparatus 200 and process the retrieved historical UVI data together with any new personal information in the mobile terminal related to UV radiation exposure and personal health. Optionally the mobile terminal 500 is configured to generate updated personal health instructions on UV exposure and protection by processing the UVI value at the present time and the historical UVI data retrieved from the monitoring apparatus 200, and additional information stored in the mobile terminal 500 including location information with local altitude and bright surface (sand, water, snow, etc.) conditions and particularly personal health information special for the authenticated user or alternative historical UVI data for the authenticated user but not saved in the monitoring apparatus 200.

Optionally, the mobile terminal 500 is configured to display the updated personal health instructions on UV exposure and protection in text. The personal health instructions on UV protection include recommended minimum exposure time, allowed maximum exposure time, application of a broad-spectrum sunscreen with sun-protection-factor (SPF) in certain level, and suggestion on seeking shade or wearing sun protective clothing, wide-brimmed hat, and UV-blocking sunglasses. For example, if the UVI value of the present time is 8, a maximum exposure time is 30 minutes and could be cut to 10 minutes if the user has been exposed before as indicated by the historical UVI data and a broad-spectrum sunscreen with SPF level in 15˜30 is recommended to be applied every 2 hours.

Optionally, the data base associated with the authenticated user in the memory 106 of the monitoring apparatus 200 can be updated after the mobile terminal 500 processes the combined data in original data base and an alternate data base assigned to the same authenticated user. An updated historical UVI data will be saved in the memory 106 of the monitoring apparatus 200. Optionally, the monitoring apparatus 200 can also display the updated personal health instructions on UV protection that is obtained based on the updated historical UVI data and a UVI value at the present time measured by the UV detector 105 thereof.

Optionally, the monitoring apparatus 200 also includes a user interface 130 configured to establish a new authenticated user data base in the memory 106 and make a link to the mobile terminal 500 of the system 1000. The mobile terminal 500 is hosted by the same new authenticated user to back up a first piece of historical UVI data obtained in the current UV exposure event by the monitoring apparatus 200.

In another aspect of the present disclosure, a method of providing personal health instructions on UV exposure and protection based on results of monitoring UV radiation at the present time as well as monitoring historical UVI data of an authenticated user. FIG. 4 is a flow chart showing a method of monitoring ultraviolet radiation for providing personal health instructions on UV protection according to some embodiments of the present disclosure. Referring to FIG. 4, the method 2000 starts with a step of collecting user identity information. Optionally, user's finger print, voice, or special sound can be collected as the user identity information for establishing an authenticated user to receive personal health instructions. For example, as shown in FIG. 1, one or more authenticators are used to collect user identity information. Optionally, the user identity information is collected as an image, or voice spectrum, or sound frequency profile. Optionally, the user identity information is in a digital format.

Referring to FIG. 4, the method 2000 further includes a process of identifying the user based on the collected user identity information. Optionally, the user identity information in digital format is processed by a controller which is configured to compare the collected user identity information with one user identity information in multiple data bases pre-stored in a memory. Each data base is assigned to one of multiple authenticated users. The comparison above leads to a process of determining whether the user identity information matched that of an authenticated user. If the user identity information matches that pre-stored for an authenticated user, an authenticated mode is enabled and a particular data base is assigned to the authenticated user for storing all user-specific data. Optionally, the data base has stored historical data specifically associated with the authenticated user which is now retrievable by a controller or utilized for providing personal health instructions for a current event. Optionally, the data base can be updated by saving newly acquired data for the current event on top of the historical data which can be utilized for any future event.

Referring to FIG. 4 again, the method 2000 includes a process of measuring intensity of UV radiation exposing to the authenticated user. The intensity of UV radiation is then used to generate a UVI value. Optionally, the intensity of UV radiation can be measured by multiple UV sensors aiming to different directions to measure both UV radiation exposures directly from sun light and indirectly from reflections of bright surfaces nearby. A UVI value at the present time is generated by converting a real-time UV intensity value based on a standard UVI definition. The UV of greatest concern for causing sunburn occupies a spectrum of wavelength primarily from 295 to 325 nm. Skin damage from sunburn, however, is related to wavelength, the shorter wavelengths being much more damaging. Therefore, weighting factors are introduced for properly taking consideration of the wavelength-dependent UV damage measurement. An integrated UV intensity is obtained using all the intermediate weighting factors over the full spectral range of 290 nm to 400 nm. Then the integrated UV intensity (in unit of mW/m²) is divided by 25 mW/m² to give a UV Index (UVI) value.

Referring to FIG. 4, the method 2000 includes a process of displaying the UVI value obtained real-time in a current UV exposure event and saving the UVI value at the present time to the data base. Optionally, the UVI value at the present time is added on top of a historical UVI data existed in the data base associated with the authenticated user. The historical UVI data includes at least a set of UVI values and corresponding exposure time. As the UVI value at the present time plus a latest exposure time associated with the current UV exposure event is added in the data base, an updated historical UVI data is obtained and saved. Optionally, the historical UVI data also contains information related to location and environment information about where a particular UVI value was obtained during a past UV exposure event.

Referring to FIG. 4 again, the method 2000 further includes a process of providing personal health instructions on UV protection based on the UVI value at the present time and the updated historical UVI data in the data base. Optionally, this process is performed by displaying the personal health instructions on UV protection in text on a display panel.

Referring back to the process of determining whether the user identity information matched that of an authenticated user, if the user identity information is determined not matching that pre-stored for an authenticated user the method 2000 includes a selection process for the user to decide to be established as an authenticated user or not. If the user selects not to be established as an authenticated user, the method 2000 includes a step of enabling an anonymous mode for the user. Optionally, the selection process is performed by a user interface coupled to a controller to send user instruction thereof. Optionally, the user interface is configured to allow the user to confirm to enter the anonymous mode. Subsequently, the method 2000 includes a process of measuring intensity of UV radiation exposing to the user under the anonymous mode. The intensity of UV radiation is then used to generate a UVI value at the present time. This process is substantially the same for the authenticated user. Finally, the method 2000 includes a process of displaying the UVI value at the present time. Optionally, this process is performed by displaying the UVI value on a display panel. Optionally, the UVI value is directly displayed as digit numerals. Optionally, the UVI value is displayed in certain color coded based on which specific range of the measured UVI value falls in.

If the user selects to be established as an authenticated user, the method 2000 includes a step of saving the collected user identity information into a memory to establish a data base associated with the authenticated user. Optionally, the user interface is configured to receive selection instruction and send to the controller. The controller is to perform the step of saving the collected user identity information into a memory based on the selection instruction. Optionally, the user interface allows the user to confirm to log in as a (new) authenticated user. Subsequently, the method 2000 includes several processes that at substantially the same as those for all authenticated users: measuring intensity of UV radiation to generate a UVI value at a present time; displaying the UVI value and saving the UVI value with corresponding exposure time as part of historical UVI data; and providing personal health instructions on UV protection based on the UVI value at the present time and all historical UVI data in the data base associated with the (new) authenticated user.

In an alternative aspect, the present disclosure provides a method of providing updated personal health instructions on UV protection by pairing the monitoring apparatus with a mobile terminal.
